Description

Technical Field

[0001] This utility model relates to the field of tray bottom plate technology, and more specifically, to a tray bottom plate for irradiation. Background Technology

[0002] An irradiation tray base plate is a support structure used to support irradiated items during irradiation processing, and is usually installed inside the tray. An existing irradiation tray with publication number CN211427862U includes a box body, which comprises a base frame, an upper crossbeam, and side frames for connecting the base frame and the upper crossbeam. The base frame, upper crossbeam, and side frames all have transverse through-holes. The upper crossbeam and base frame are rectangular. Four side frames are positioned opposite each other at the edges of the base frame and upper crossbeam. Side plates are fixed to each side frame, forming a channel with openings at the top and bottom. The outer surfaces of the side plates and side frames are on the same plane. A support portion is provided on the bottom inner side of the base frame, with the support portions horizontally opposite each other. A base plate is placed on the support portion, and the shape of the base plate matches the interior of the channel. The height of the upper surface of the base plate is lower than the opening located in the base frame.

[0003] However, in the above scheme, the bottom plate of the irradiation tray is supported by the support part. Due to the suspension or insufficient support in the middle of the bottom plate, the middle of the bottom plate is prone to bending, denting or even breaking under the pressure of heavy objects when the bottom plate is under load. Utility Model Content

[0004] The main purpose of this utility model is to provide a bottom plate for an irradiation tray, which can effectively solve the problem in the background art where the bottom plate of the irradiation tray relies on a support part for support, and the middle part of the bottom plate is suspended or insufficiently supported, so when the bottom plate bears a heavy load, the middle part of the bottom plate is prone to bending, denting or even breaking under the pressure of the heavy object.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A tray base plate for irradiation includes a tray plate, wherein two mounting blocks are fixedly installed on both sides of the upper surface of the tray plate, and each mounting block has a through mounting hole on one side surface;

[0007] The lower surface of the tray is provided with several support components for support.

[0008] Preferably, the support assembly includes several rotating shafts, which are rotatably mounted on a corresponding side of the lower surface of the support plate. A rotating plate is fixedly mounted on the lower end of the rotating shaft, and a support frame is fixedly mounted on both sides of the rotating plate. A support block is provided at the lower end of the support frame.

[0009] The upper surface of the rotating plate is provided with a clamping structure.

[0010] Preferably, the clamping structure includes a connecting hole that extends through the upper surface of the rotating plate. A threaded sleeve is rotatably installed in the connecting hole via a bearing. A threaded rod is threaded inside the threaded sleeve. Two positioning blocks are fixedly installed on one side of the threaded rod. Positioning rods are fixedly installed on the lower surface of each of the two positioning blocks. A positioning hole is provided on the upper surface of the rotating plate, and the two positioning rods are slidably disposed in the corresponding positioning holes.

[0011] Preferably, a limiting block is fixedly installed on one side of the lower surface of each rotating plate, a rotating rod is rotatably installed through one side of each limiting block, a rotating wheel is fixedly installed at one end of each rotating rod, a first bevel gear is fixedly installed at the other end of each rotating rod, and a second bevel gear is sleeved on one side of the threaded sleeve, with each first bevel gear meshing with the corresponding second bevel gear.

[0012] Preferably, each of the support frames has a threaded hole on its lower surface, and a stud is threaded into each of the threaded holes. The lower end of each stud is fixedly connected to the corresponding support block.

[0013] Each stud is fitted with a hexagonal rotating block.

[0014] Preferably, the outer wall surface of the pallet is provided with spherical grooves, and a rotating ball is rotatably installed in each spherical groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The operator rotates the rotating plate so that it rotates around the rotating shaft, thereby rotating the threaded rod to the lower end of the position of the heavy object. Then the operator controls the threaded sleeve to rotate.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0025] like Figures 1-6 As shown, a tray base plate for irradiation includes a tray 1, and two mounting blocks 2 are fixedly installed on both sides of the upper surface of the tray 1. Each mounting block 2 has a mounting hole 3 through one side surface.

[0026] The lower surface of the tray 1 is provided with several support components 4 for support.

[0027] Support assembly 4 includes several rotating shafts 401, which are rotatably mounted on the corresponding side of the lower surface of the support plate 1. A rotating plate 402 is fixedly mounted on the lower end of the rotating shaft 401, and a support frame 403 is fixedly mounted on both sides of the rotating plate 402. A support block 404 is provided at the lower end of the support frame 403.

[0028] The upper surface of the rotating plate 402 is provided with a clamping structure 405.

[0029] The clamping structure 405 includes a connecting hole 4051, which is opened through the upper surface of the rotating plate 402. A threaded sleeve 4053 is rotatably installed in the connecting hole 4051 through a bearing 4052. A threaded rod 4054 is threaded inside the threaded sleeve 4053. Two positioning blocks 4055 are fixedly installed on one side of the threaded rod 4054. Positioning rods 4056 are fixedly installed on the lower surface of each of the two positioning blocks 4055. A positioning hole 4057 is opened on the upper surface of the rotating plate 402. The two positioning rods 4056 are slidably installed in the corresponding positioning holes 4057.

[0030] The worker secures the pallet 1 inside the pallet box by passing the bolt through the mounting hole 3 and fixing it in the working position. Then, the worker rotates the rotating plate 402, making it rotate around the rotating shaft 401 as a reference, so that the threaded rod 4054 rotates to the lower end of the position where the heavy object is located. Then, the worker controls the threaded sleeve 4053 to rotate. The rotating threaded sleeve 4053 drives the threaded rod 4054 to move along the direction of the positioning rod 4056 by the threaded advance. This allows the threaded rod 4054 to press against the bearing position on the lower surface of the pallet 1 according to the position of the heavy object. With the support of the support block 404 and the threaded rod 4054, the middle position of the pallet 1 can be supported, preventing the middle position of the pallet 1 from denting or even breaking when bearing heavy objects.

[0031] In another embodiment of this utility model, a limiting block 5 is fixedly installed on one side of the lower surface of each rotating plate 402, and a rotating rod 6 is rotatably installed through one side of each limiting block 5. A rotating wheel 7 is fixedly installed at one end of each rotating rod 6, and a first bevel gear 8 is fixedly installed at the other end of each rotating rod 6. A second bevel gear 9 is sleeved on one side of the threaded sleeve 4053, and each first bevel gear 8 meshes with the corresponding second bevel gear 9.

[0032] The operator rotates the rotating wheel 7, which drives the rotating rod 6 to rotate. Under the meshing action of the first bevel gear 8 and the second bevel gear 9, the threaded sleeve 4053 rotates, making it convenient for the operator to control the rotation of the threaded sleeve 4053.

[0033] In another embodiment of the present invention, each support frame 403 has a threaded hole 10 on its lower surface, and each threaded hole 10 has a threaded stud 11 threaded in it. The lower end of each stud 11 is fixedly connected to the corresponding support block 404.

[0034] Each stud 11 has a hexagonal rotating block 12 fitted onto its shaft.

[0035] The operator rotates the hexagonal swivel block 12, causing the stud 11 to rotate. The rotating stud 11 moves along the threaded hole 10, allowing the operator to adjust the height of the support block 404 according to the height of the pallet 1.

[0036] In another embodiment of this utility model, a spherical groove is provided on the outer wall surface of the tray 1, and a rotating ball 13 is rotatably installed in each spherical groove.

[0037] By setting a rotating ball 13, when the operator removes the bolts and adjusts the position of the pallet 1, the sliding friction between the outer wall surface of the pallet 1 and the inner wall surface of the box is changed to rolling friction, thus avoiding severe wear on the surface of the box and the outer wall surface of the pallet 1.

[0038] The working principle of a tray base plate used for irradiation:

[0039] In use, the operator passes the bolt through the mounting hole 3 and then fixes the bolt in the working position, thereby fixing the pallet 1 inside the pallet box. Then, the operator rotates the rotating plate 402, making it rotate around the rotating shaft 401 as a reference, so that the threaded rod 4054 rotates to the lower end of the position where the heavy object is located. Then, the operator controls the threaded sleeve 4053 to rotate. The rotating threaded sleeve 4053 drives the threaded rod 4054 to move along the direction of the positioning rod 4056 by the threaded advance. This allows the threaded rod 4054 to press against the bearing position of the lower surface of the pallet 1 according to the position of the heavy object. With the support of the support block 404 and the threaded rod 4054, the middle position of the pallet 1 can be supported, avoiding the dent or even breakage of the middle position of the pallet 1 when bearing heavy objects.

[0040] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
